Title: Device and method for aligning and inserting a threaded fastener
Inventor: BECK JOSEPH L
IPC: B25B11/00
Filed: 2012-03-27
Abstract: A device and method for aligning and inserting a threaded fastener into a threaded hole. The device contains a base and a rail extending up from the base. A gearbox may be attached to the rail such that the gearbox can travel along the rail between a fastener loading position, a fastener install position, and a fastener realigning position. A socket assembly is connected to or otherwise associated with the gearbox and includes a drive socket that is adapted to accept the threaded fastener and an input shaft which is adapted to translate rotational motion to the output socket. A spring mechanism is attached to the gearbox and contains a spring that will compress when the gearbox travels into the fastener realigning posi6on. A compressible washer may be interposed between the output shaft and the drive socket of the socket assembly so that the central axes of these components may be misaligned without causing damage or disrupting the alignment process.

Title: Systems and devices for evaluating the integrity of a uterine cavity
Inventor: TOTH AKOS
IPC: A61B5/117
Filed: 2010-11-11
Abstract: Methods, systems and devices for evaluating the integrity of a uterine cavity. A method comprises introducing transcervically a probe into a patient's uterine cavity, providing a flow of a fluid (e.g., CO2) through the probe into the uterine cavity and monitoring the rate of the flow to characterize the uterine cavity as perforated or non-perforated based on a change in the flow rate. If the flow rate drops to zero or close to zero, this indicates that the uterine cavity is intact and not perforated. If the flow rate does not drop to zero or close to zero, this indicates that a fluid flow is leaking through a perforation in the uterine cavity into the uterine cavity or escaping around an occlusion balloon that occludes the cervical canal.

IPC: C09B56/12
Filed: 2011-03-09
Abstract: The invention provides a method of improving the digestion of wood chips into pulp. The method involves: adding a liphohydrophilic glycerol-based polymer additive to a solution used in the digestion process. This additive is unexpectedly effective at facilitating digestion. The branched and ether structure of the additive allows it to withstand the harsh nature of a highly alkaline environment. In addition, it is more soluble in high pH than other surfactants. The structure, resistance, and particular balance between hydrophobic and hydrophilic regions, causes the additive to increases the interaction between the wood chips and the digestion chemicals. This in turn reduces the costs, the amount of additive needed, and the amount of reject wood chunks that result from the digestion process.

Abstract: A process for separating polyunsaturated fatty acids (PUFAs) such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) from less saturated long chain fatty acids (LCFAs) in a lipid composition, wherein said PUFAs and LCFAs are present as (i) triglycerides, or (ii) free fatty acids or monoalkyl esters, by exchange of at least a portion of LCFAs with short and/or medium chain fatty acids (MCFAs). The process can suitably be employed on marine derived oil, marine oil 2 derived oil products and other sources of PUFAs, including PUFA-rich singe cell oils (SCOs), and oils from genetically modified organisms with a modified lipid metabolism. The inventive process is based on novel use of lipases and distillation techniques, selectively chemically modifying species in the substrate material such that the desired species and chemically similar species become sufficiently dissimilar to be separable. Thus PUFA can be effectively enriched from material such as 30 herring oil with low PUFA content and high contant of equal length monounsaturated fatty acids such as 20:1 and 22:1 fatty acids.

Title: Ash and solids cooling in high temperature and high pressure environment
Inventor: VIMALCHAND PANNALAL
IPC: C10J3/56
Filed: 2011-08-05
Abstract: Disclosed are cooling and depressurization system equipment, arrangement and methods to cool solid particles from a coal gasifier operating at high temperature and pressure. Ash from the coal needs to be continuously withdrawn from a circulating fluidized bed gasifier to maintain the solids inventory in the gasifier. The system disclosed enables use of conventional materials of construction for heat transfer surfaces. The supports for the cooling surfaces are located on the lower temperature upper section of the primary cooler. The cooled solids along with the fluidizing gas exits the primary cooler to a secondary receiving vessel where the solids can be further cooled by conventional means. The fluidizing and entrained gas entering the secondary vessel is filtered and vented through a vent pressure control valve. The column of cooled solids in the secondary vessel is depressurized by a continuous depressurization system to low pressures which are sufficient for conveying the solids to silos for disposal. The system and methods proposed are equally applicable to many high temperature, high pressure processes that require cooling and depressurization of process solids.

Abstract: A process for optimizing the carbon feed in a denitrification filter. The process utilizes in-line or off-line measurements of process variables in combination with feed forward and feedback control and increases or decreases the amount of carbon added based on a calculated reset rate determined on a periodic basis. The calculated reset rate may be a percentage of a theoretical value of the necessary carbon feed rate needed to remove the desired amount of nitrate-nitrogen. When the effluent nitrate-nitrogen is at a desired level and no rate change is necessary, the carbon feed rate is set to an average of one or more of the last filter runs. The process may also include a step wherein the carbon addition is increased immediately after backwashing to reestablish the biomass needed to produce the desired effluent in a step to regain process efficiency once that boost reestablishes the biomass.
